I came across this excellent User Interface Kit via Jeffrey Zeldman’s site and thought you’d would find it useful too. The kit is available to download for free from Webalys and includes tons of handy GUI elements for use in Adobe Illustrator.
All of the elements can be customized and tweaked to your own desires. The kit can be used by designers working in Illustrator to design mockups, wireframes and application interfaces. You can add them to illustrator as Panels or pick them from the library files.
The designers of the kit have been most generous and in relation to payment for the kit say:
This framework is released as a complete web designer kit for free. Even for commercial use.
I just require a link to this page if you use the elements, icons or styles on a online website :http://www.webalys.com/design-interface-application-framework.php
You don’t need to make a link if you use it only in application wireframes or user interface mockups.

260 Vector Icons Library
- A pixel precise icon collection created for interface designers and web designers.
- All icons can be adapted and can be used for website wireframes, online application design, software interface mockup.
- Icons are based on a precise 16 pixels grid, ensuring which means that they stay clear and have crispy look even at small sizes.
